[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example
[0026] like Figures 1-7 As shown, a variable diameter hemming guide for garment processing includes: a machine base 1, a sewing machine 101 mounted on the top of the machine base 1, a hemming device 102 disposed on one side of the bottom of the sewing machine 101, and a replacement component disposed on one side of the hemming device 102, the replacement component including: a mounting head 2, a U-shaped sleeve 201, a limiting groove 202, a fixing block 203, a rotating arm 204, a fixing strip 205, a limiting screw hole 206 and a tightening screw 207, and a limiting component disposed on the top of the machine base 1, the limiting component including: an insertion hole 3, an insertion rod 301, a gripper head 302, a rubber sleeve 303 and a positioning hole 4.
[0027] The edge curler 102 has an installation head 2 on one side, and a U-shaped sleeve 201 is installed at one end of the installation head 2. A limit groove 202 is opened on the top of the U-shaped sleeve 201. A fixing block 203 is installed on the top of the machine base 1. A rotating arm 204 is provided on one side of the top of the fixing block 203. A fixing strip 205 is installed on the outer end of the rotating arm 204. Multiple limit screw holes 206 are opened on the top of the fixing strip 205. A tightening screw 207 is provided on the top of the limit groove 202.
[0028] When using the sewing machine 101, first install the fixing block 203 on the machine base 1, with the fixing strip 205 on the top of the fixing block 203 suspended between it and the machine base 1. Then, place the U-shaped sleeve 201 at one end of the mounting head 2 onto the fixing strip 205. Insert the tightening screw 207 into the limiting groove 202, so that the bottom of the tightening screw 207 contacts the limiting screw hole 206. Tighten the tightening screw 207 inside the limiting screw hole 206, and fix the U-shaped sleeve 201 onto the fixing strip 205. Then, place the hemming tool 102 securely on the machine base 1 and align it with the presser foot at the bottom of the sewing machine 101. The hemming tool 102 can curl the edge of the fabric and guide it to the stitch for sewing. Using the hemming tool 102 can greatly improve sewing efficiency, while ensuring the consistency and accuracy of the hemming, and reducing errors that may occur during manual operation.
[0029] When it is necessary to replace the hemming tool 102 with a different shape, loosen the tightening screw 207 in the limiting groove 202 and remove it to release the limiting fixation between the U-shaped sleeve 201 and the fixing strip 205. The U-shaped sleeve 201, the mounting head 2 and the hemming tool 102 can be removed, so that the hemming tool 102 can be disassembled separately. It is convenient to replace the hemming tool 102 with a different shape according to the usage requirements. The disassembly and assembly are convenient, achieving the purpose of saving time and effort and improving the work efficiency of fabric hemming and sewing.
[0030] The fixing block 203 has a fixing groove 210 on its top, and a fixing screw 211 is provided on the top of the fixing groove 210. The machine base 1 has a fixing screw hole 212 on its top. When installing the fixing block 203, the fixing block 203 is placed on the top of the machine base 1, so that the fixing groove 210 on the top of the fixing block 203 is aligned with the fixing screw hole 212 on the top of the machine base 1. Then, the fixing screw 211 is inserted into the fixing groove 210, so that the bottom of the fixing screw 211 contacts the fixing screw hole 212. The fixing screw 211 is rotated and tightened inside the fixing screw hole 212, so that the fixing block 203 is fixedly installed on the machine base 1 to prevent the fixing block 203 from loosening and shifting, and to ensure that the edge curler 102 has good stability during use.
[0031] The top outer circumferential surface of the loosening screw 207 is provided with several anti-slip textures 208, and the top of the loosening screw 207 is provided with a groove 209. When fixing the U-shaped sleeve 201, during the process of holding the loosening screw 207 and rotating it to tighten it inside the limiting screw hole 206, the hand comes into contact with the anti-slip textures 208 on the top outer surface of the loosening screw 207, which can prevent the hand from slipping on the loosening screw 207. This allows the loosening screw 207 to be tightened quickly inside the limiting screw hole 206. The groove 209 also allows a screwdriver to be inserted into the groove 209 to rotate the loosening screw 207 under force, preventing the screwdriver from slipping on the loosening screw 207, thus achieving time-saving and labor-saving disassembly and assembly.
[0032] The top of the fixing strip 205 is provided with a scale layer 6, which is directly opposite to the limiting groove 202. When it is necessary to adjust the hem roller 102 to align with the presser foot at the bottom of the sewing machine 101, the U-shaped sleeve 201 can be slid left and right on the fixing strip 205. The setting of the scale layer 6 can reduce the time for manual comparison, quickly adjust the position of the hem roller 102 to align with the presser foot, and then fix the U-shaped sleeve 201 to the fixing strip 205.
[0033] The fixed block 203 has a rotating hole 5 on one side of its top. The rotating arm 204 is equipped with a rotating shaft 501 that is rotatably connected to the rotating hole 5. When the hem roller 102 is not needed for hemming and sewing the fabric, the hem roller 102 is pulled to the right. At this time, the U-shaped sleeve 201 will drive the fixed strip 205 and the rotating arm 204 to rotate under force, so that the rotating arm 204 rotates through the rotating shaft 501 and the rotating hole 5 on the top of the fixed block 203. This allows the hem roller 102 to be rotated away, so that the hem roller 102 can be removed from the outer end of the presser foot without affecting the normal sewing of the fabric. When the hem roller 102 is needed for hemming and sewing the fabric, the hem roller 102 is pulled to the left and rotated to the outer end of the presser foot, so that it is aligned with the presser foot.
[0034] The rotating arm 204 has an insertion hole 3 at its top, an insertion rod 301 inside the insertion hole 3, a gripper head 302 installed on the top of the insertion rod 301, a rubber sleeve 303 fixed to the outside of the insertion rod 301, and a positioning hole 4 on one side of the fixing block 203.
[0035] When the hemming tool 102 is aligned and used with the presser foot, the insertion rod 301 is inserted through the insertion hole 3 at the top of the rotating arm 204 into the positioning hole 4. The rubber sleeve 303 on the outside of the insertion rod 301 is the same size as the insertion hole 3 and the positioning hole 4, so that the insertion rod 301 can be stably inserted into the insertion hole 3 and the positioning hole 4, limiting and fixing the rotating arm 204, preventing the rotating arm 204 from rotating, avoiding the hemming tool 102 from swaying and shifting, and ensuring that the hemming tool 102 has good stability during the hemming and sewing process of the fabric. When the hemming tool 102 is not needed, the insertion rod 301 and the rubber sleeve 303 can be directly pulled out from the insertion hole 3 and the positioning hole 4 to release the limiting and fixing of the rotating arm 204, so that the rotating arm 204 can drive the fixing strip 205, the U-shaped sleeve 201, the mounting head 2 and the hemming tool 102 to rotate and move away.
[0036] Working principle:
[0037] When using the sewing machine 101, first install the fixing block 203 on the machine base 1, with the fixing strip 205 on the top of the fixing block 203 suspended between it and the machine base 1. Then, place the U-shaped sleeve 201 at one end of the mounting head 2 onto the fixing strip 205. Insert the tightening screw 207 into the limiting groove 202, so that the bottom of the tightening screw 207 contacts the limiting screw hole 206. Tighten the tightening screw 207 inside the limiting screw hole 206, and fix the U-shaped sleeve 201 onto the fixing strip 205. Then, place the hemming tool 102 securely on the machine base 1 and align it with the presser foot at the bottom of the sewing machine 101. The hemming tool 102 can curl the edge of the fabric and guide it to the stitch for sewing. Using the hemming tool 102 can greatly improve sewing efficiency, while ensuring the consistency and accuracy of the hemming, and reducing errors that may occur during manual operation.
[0038] When it is necessary to replace the hemming tool 102 with a different shape, loosen the tightening screw 207 in the limiting groove 202 and remove it to release the limiting fixation between the U-shaped sleeve 201 and the fixing strip 205. The U-shaped sleeve 201, the mounting head 2 and the hemming tool 102 can be removed, so that the hemming tool 102 can be disassembled separately. It is convenient to replace the hemming tool 102 with a different shape according to the usage requirements. The disassembly and assembly are convenient, achieving the purpose of saving time and effort and improving the work efficiency of fabric hemming and sewing.
[0039] When the hem roller 102 is not needed for hemming and sewing the fabric, pull the hem roller 102 to the right. At this time, the U-shaped sleeve 201 will drive the fixing strip 205 and the rotating arm 204 to rotate under force, so that the rotating arm 204 rotates through the rotating shaft 501 and the rotating hole 5 at the top of the fixing block 203. This allows the hem roller 102 to be rotated away, so that the hem roller 102 can be removed from the outer end of the presser foot without affecting the normal sewing of the fabric. When the hem roller 102 is needed for hemming and sewing the fabric, pull the hem roller 102 to the left and rotate it to the outer end of the presser foot, aligning it with the presser foot.
